The piston is joined to one contact of the circuit breaker and the cylinder to the other contact. Both contacts are connected to an operating device which is adapted, during the first part of a breaking operation, to move the contacts in opposite directions away from each other, whereupon one contact and the piston joined thereto are returned to the initial position.
